CESSPOOL.

Toall 'whom it may concern.:

Be it' known 4that I, Pmmr M'iinnnnn, a

i f .citizen of the United States, residing at Decatur, in the county of Macon and State ot' Illinois, h'ave invented newv and usefuL'Imroi-'ements in (lesspools, of which the folowing is a specification.

'My invention relates toa cesspool for ,i Hoor use, and particularly to one adapted for use in the operating rooms of hospitals.

It is very desirable and in some eases essen- Y tial that such floors be well drained and that they sho'uld he. Aso constructed and equipped I aste he' easily andv readily cleaned and -`placed in first-class vsanitary condition. At the present time the floors are 'commonly made sloping toward a certain pointfrom which a drain pipe leads, this drain pipe being usually equipped with a strainer some- 2C' times flush with the floor and sometimes not,

.for preventing thc'drain pipe from becoming clogged by solid substances.- It fre- A quently happens, however, that this strainer f is-broken, displaced and-lost with the result 'v25-thzit`the -drain pipe thus becomes clogged and soon reaches an unsanitary condition.

Fprther trouble is experienced with these' fdra'in pipes as commonly installed owing to .he factthat their inletl ends at the floor are `located some distance awayfrom the trap, the'trap being often times located eightl or tcnl'feet away from the opening and adjacet'the delivery ofthe pipe linto. the sewer. Int-such cases particularly when the drain '85- pipe is substantially horizontal or has little slope, the drainagcof the pipe is notcomfi 'plete and that portion of it which adheres to the walls of the pipe is added to at each draining of the tloor and the pipe soon 40 reaches an unsanitauiI condition, obnoxious and unpleasant gases being emitted to the room through the open end of the pipe. A Similar condition is often found when the discharge pipe. instead of being led to a :s S'ewer is lcd to other point. of discharge and is without traps of any kind.

- The objectof my invention is to produce a cess-pool for liospitalsby theuse of whichy the above named troubles may be a vided.`

Th c ool which I have invented wholly avoidsj ose troubles, and is possessedl of many advantages which make it an eicient and valuable product. invention consists of a Hoor basin adapted to beplaced in a. tiooi' and Et with Specification of Letters Patent.

its upper edge flush with the surface of the Hoor. This basin I construct of aniple'proportions which, of course, may be Varied according to the size of the floor or the size of the drain pipe to be used in connection I with it.- Just at the bottom of the basin and contiguous to it I provide ay trap which communicates direct] With'the basin. The escape into a room ot. obnoxious gases from the section of the drain pipe leading tothe l sewer, as well as gases from the sewer, is. thus eflectually prevented. By locating this trap contiguous' to th basin I especially adapt it for tloor use as there is not, room in- :most instances owingsto the small space be- 'tween ceiling and superposed floor in most,

building constructions to properly'locate a trap with respect to ay drainage asin in any Within the basin above the trap opening but below thesurfaee of the Hoor, I provide a strainer. By virtue of its position within the basin there is no danger of its being displaced accidentally. An at- `tached cover of special construction tits the top of the basin snugly and covers the cesspool and its-parts when not in use, the top of the cover being flush with the surface of the floor. This cover is locked down ti htly by a special locking mechanism which v1s be-, neath the cover, but which is adapted to be operated from the outside by av suitable keyV which I prefer to connect with the mechanism and cover and make flush with the top of the cover. Thus when the cover is in place it forms a part of the floor, and therer is no projectionv above it which mightfbc in the Way.

The full advantages of my improved cesspool together with the various details of construction thereof, will be readily a arent from the following description 'takenrllii conneetion with the accompanying drawings, in which-f f Figure 1 is a-central sectional elevation of vtl'te same equipped with one form of cover 100 locked in place. Fig. 2 is-a similar view, showing \thcover in raised position and the mouth of the cesspool open. Fig. 3 is a 'view of the underneath -side of the cover Vshowing the hinge vand lever connections.

Fig. 4 is a detail of -the locking key, and its connection to the locking levers. Fig. 5 is a view of theunderneath side of the strainer I use. Fig. 6 is a sectional side elevation of the same. Figs. 7 .and Bare plan and sec- 11o Y main body some distance above its bottom tional elevation respectively, of a modified form of locklng means for use with the cover, and Fig. t) shows in section a modified4 other and with the floor 'ring 11, and within thc-lowermost shelf '14 is formed a concentric`opening 15.

l From the lowermost. shelf 14, and projectingthrough the opening 15 is a main body 1G of the trap, This main body makes a tight joint with the shelf 14, solder 17 being used for this purpose, and in the side of the is a discharge opening 1S; this discharge opening, 'most desirable.

Supported from the shelf A13 by means of its flange 1S) is a sectional member 2 0 of the trap which is preferably concentric with the main body andd'oes not reach quite to its bottom, but does reach below the discharge opening 1S. The drainage which enters the trap, therefore, passes through the member 20 and thewater seal which is formed inthe main body, and whose level is the lower wall of the discharge opening, andthen passes through the discharge opening tothe sewer. The white leaded joint is made between tlie 'member 20 andthe shelf 13,'a concentric tongue and groove 21: being formed between the flange 19 and the shelf 13, and screws 22 being used to firmlyl screw the lmember 20 in place.l By the simple removal of the screws 22, however, the member 20 may be removed from Within the basin, and free access can be had to the main body of the trap or the sewer for cleaning the same.

The shelf 12, which is the uppermost of the three Ashelves 12, '13 and 14, carries a strainer 23. This strainer I prefer to make in the forni of a plate as shown, the plate being cast or otherwise made inthe shape shown in Figs. 5 and 6, and'provided with a plurality of tapering holes, the walls of the hole forming in outline a frusto-conical figure, and the small ends of the. holes all lying on one side of the plate. 'This strainer I position within the basin of the 'cesspooh I as shown in Figs. 1 and 2. a side of the plate with the small ends of the holes being the top of the strainer. I find that when so -formed and used this strainer is most sani-4 tary. The drainage passing through the strainer falls from4 it and unobstructed through the large ends ofthe straining holes. There is thus but little tendency for drain- This basin is a pted of course, I may'locate as I find'- age to accumulate on the walls of the holes, as it does not under `ordinary conditions touch ftheni. Such little, however, as does ,accumulate, is on the underl side of the strainer and not exposed to View, as would be the case if the holes were tapered in the opposite' direction, and the strainer thus presents a cleanly appearance at allt-imes. It will be'notedthat this strainer simplyrests yupon the shelf 12 by gravity, and it may thus be removed at will for cleansing it and for cleansing the underneath'port-ions of the, basin.

As thus constructed the cess'pool is com-l plete as far as is'ne'cessary for it to perform its functions as a cesspool. I' prefer, however, to provide the cesspool with a. jcove'r, which fits flush with the surface of the floor and hides the pool 'from `view as wellaspre, vents the receipt/'of foreign matter byfit,

when it is not in use.' This cover is indi` catedat 24.' A hinge link 25 1s lhinged at one end to a'lug 2G'within the' n iouth of the basin and at the other'end to 1a lug L27 de; peuding'from the'under side of the' coYer 2l and approximately at its center- The link w 25 is preferably formed in anl H-sha'ped form as clearly shown in Fig. 3. The cover` is ribbed on its 'under side 'inlorder t 0` strengthen it,fiv.e or sixribs 28 beingshown for thislpurpose, and one of ythem 29.isc" ift away to accommodate'th'e cross-bar'fBQof" the link member 25 when the .cover2 is in*4 closed position. Also hinged tofthiug 27*-` is a locking'lever 31 for locking or clainpintigv the cover in place, this lever extending'to lthe side of the basin and bearing at rits outer end againsta lug 32.' Shortof this end'it has 'formed within it a hole I which passes a clamping screw`34 which* 10 5 enters a screw threaded cavity A"'3'5`i1'1-7the 'body of. the hasinand is provlded wlth a thumb-piece 36 on its. upper end.r 'This screw or bolt is 4provided -at its upper -end` with an -enlarged portion '36 which bears" against the upper side of the locking lever` 31, the large portion heingof too great di` ameter to pass through the, hole 33.'l Vhenthe screw is turned bythe thumb-piece' right` handedly it travels downwardly, and 'be'ar ing against the upper side'of the locking' lever 31 turns it about the lug 32 asafulf vcrum and brings pressure to bearfon the'\ lug 27 on' the under side of the cover, thus locking it in place. Preferably the edges'r37 20 of the cover and the cooperating edge ofthe basin are Ybeveled asy is approximately,in the centerofthe. cover a firm even pressure is brought to bertrand a close tight joint of the cover with the'basin 125 secured. When itis desired to open the pool. for use the screw 34 is simply turned until it is released by the screw threads at its lower 4end and thereafter the cover may be swung upward and backward on its link 25,l

the position of the parts being as shown in F ig.- 2. As the coveris secured to the basin. by the' .liiikg25 it is always in place, and

there isnddanger of' its being lost. The

` peculiar vsha'ptijof' the link 25 gives reat stabilityarid..keeps the cover. accurate y iii alneinentfg. y v

v'llie's'crew 3 4: forms .what I term the key of m V locking' device lproperly. I so associate t islrey witlr` the cover and locking lever' that it' cannot .be readily removed therefrom. To this endv I use a set screw 34 as' shown in Fig. 4 which passes through the' construct-ion the top ofthe cover is countersunk to receive the retaining flange 38 formed on the top of the screw and a slot 39 is provided for the operation of lthe key by a screw driver or other suitable tool, as such a tool is nearly always at hand or canbe easily provided. This form of key is almost as convenient for o eration as the form shown in Fig. l, an possessesthe advantage that it is entirely out of the way and presen-ts #much neater appearance. is also less likelihood of the accumulation of dust and dirt around it. In connection with the screw threaded cavity 35 with all forms of keys I provide an out-let 22l which communicates with the bottom ofthe cavi-ty, for the purpose of expelling from the cavity any contents which it may have received during the use of the cesspool. When the keys are forced home these'contacts are eX-.

pelled through lthe opening 22n into the body of the pool. 'f:-:, i i

In Figs. 7 and 8-1 have shown a modified form ofgloc ing'means for the cover. This consists '-rof a simple diametrically placed cross bar 40, which is preferably located below the strainer 23, as shown, being screwed down at its ends to a shelf 12, of the basin, which is formed to accommodate it. At the center of the bar is formed a screw threaded hole 4l, which accommodates the end of a clamping screw 42 which passes centrally. through the cover and through the strainer, its slot-ted head being flush with the top of .the cover, as in the case of the keysffor I prefer to associate this screw with the cover by securing it thereto.

through the body of the screw just below the cover.. This prevents Ithe screw being removed and lost. In some instances I may locate the-transverse v,bar above the strainer, but I prefer to locate it beloyv the strainer' for the reason that the basin' is then more There. t0

To Ithis end' I pass a p in 42" easily cleaned, and presents a neater appearance.
